On the basis of the algorithm of maximum likelihood in the asymptotic Markov approximation the analytical equations for the output effect of the optimum (quasioptimum) filtering device are received. This device provides the maximum possible signaltonoise ratio (suppression of nonGaussian noise, decorrelation of noise and optimum matched filtering of a signal in white Gaussian noise).

For the first time in the theory of fastening of solidstate freight the case when the freight makes the movement relative to the floor of the car with the set acceleration and at this moment its speed is also known is considered. Results of the analytical description of movement of freight relative to the car are stated. It is established that at the accounting of force of inertia in the relative movement there will be less shift of freight across the car, lengthening and efforts of each flexible element.

The force diagram of the rectifierinverter transducer of an electric locomotive on the basis of power IGBT modules and its control system are described. Such upgrading allows to reduce considerably the reactive power of an electric locomotive at the expense of the change of an angle of phase shifting between input current and voltage, therefore, to increase electric locomotive power factor in a traction mode.

The issues of improvement of passenger servicing on railway transport objects by the means of adaptation and application of the modern equipment and technologies in the field of client servicing are examined. The calculation method of efficiency of application of the passenger queue management system in booking offices is offered.
S.B. Lyovin
A new approach to the formation of optimum management structure of the transport company providing the highlevel logistic services is offered. It is based on the application of the theory of the cluster analysis and composed of several stages.
A.S. Gershval'd
The mathematical problem definition of calculation of the application for train locomotives in the online mode is offered. The heuristic algorithm of information processing using simulation models of current state of the marshalling yard is developed. The task is entered in the information technology of the station traffic controller and calculated on the decision as a part of information system of daily planning.

The approach to the operation of empty cars yard by the operator company is considered in the article. This approach is based on the idea of the balance of resource flows. The formulation of mathematical model of the optimization control of empty cars yard on the criterion of a minimum of resource expenses is given.

The possible approach to model construction of the human influence assessment on the functioning of the manmachine systems based on the cognitive modeling methodology is considered. The formalization of procedures for the human influence analysis in the "mantechnical systemoperational environment" system for their further integration into the risk management system introduced currently in JSC "RZD", will allow to increase the quality and risk analysis assessment, and, respectively, to provide the required level of safety on a railway transport.

The operation of the modern equipment and means of transport is accompanied by the considerable noise and vibration level which is negatively influencing on the human health status. From the point of view of safety the noise and the vibration are one of the most general harmful factors in passenger cars.

Lading devices with a rotaryvane feeder have a wide circulation as the processing equipment for bulk freight loading in containers. The general technique of determination of power inputs connected with operation of known types of the lading devices with a horizontal axis of rotation of a rotaryvane rotor is developed.

The problem of increase in a resource of railway wheels and rails is considered. In contrast to known methods it is proposed to exclude breakin modes with high initial wear rate by giving the tread of geometric shape of natural wearandtear which corresponds to the wear resistance maximum. Determination methods of optimal forms are constructed on variational principles.
